Our Series 4 of OCCA Weekly Webinars continues with "Compatibilizers - If colorant and base do not go together" presented by Frank Kleinsteinberg of Evonik.
This webinar is free to attend, simply register below and you'll receive further details & joining instructions in due course.
Pigment concentrates get more and more popular in coatings production. These colorants make the coatings production much more flexible. Even a small amount in special colours can be delivered at reasonable cost.
The only issue is when the chosen colorant is not compatible with the base paint. Beside gloss reduction severe pigment flocculation can occur.
The lecture will give an overview about products that can be used in different production stages to overcome the incompatibility between colorant and base paint.
